通过js模拟post提交
1:请求需要的参数过长,超过get允许的最大长度
2:想要隐藏地址栏的参数
//新创建一个form表单document.write("<form name=myForm></form>"); var myForm=document.forms["myForm"]; myForm.action="runEmpAttendance"; myForm.method="POST"; var input = document.createElement("input");input.type = "text";input.name = "userId";input.value = 100;myForm.appendChild(input);myForm.submit();//使用jsp中已经存在的form表单,添加其他的参数var myForm = document.forms["listEmployee"]; //表单的namevar input = document.createElement("input");input.type = "hidden";input.name = "currentPage";input.value = 1;myForm.appendChild(input);myForm.method= "POST";myForm.submit();
